Abstract

The invention relates to a security element in the form of a flexible, multilayer film body and to an identification system comprising a security element of this type. The security element has a receiving unit (61) for receiving an electromagnetic verification signal (7) containing a specific coding from a verification device, an output unit (66) for outputting an enable signal, and an electronic release system (63, 64, 65) having active and/or passive organic components. The electronic release system (63, 64, 65) checks whether or not a signal received by the receiving unit contains the specific coding, and drives the output unit (66) for outputting the enable signal if the signal received by the receiving unit (61) contains the specific coding.

Claims

1. A security element (3) in the form of a flexible multilayer film body, comprising:

a receiving unit for receiving an electromagnetic verification signal containing a specific coding from a verification device;

an output unit for outputting an enable signal; and

an electronic release system having active and/or passive organic components, wherein the electronic release system is configured in such a way that it checks whether or not a signal received by the receiving unit contains the specific coding, and drives the output unit for outputting the enable signal if the signal received by the receiving unit contains the specific coding, and in that the output unit has at least one electrochromic element, a thermochromic element, an electroluminescent element, an electrophoretic element, a liquid crystal element or an organic light emitting diode.

2. The security element as claimed in claim 1, wherein the output unit has a piezoelement for generating a sound signal or a signal that can be detected by a tactile device.

3. The security element as claimed in claim 1, wherein the output unit is configured for generating a signal that can be detected thermally or by the sense of smell.

4. The security element as claimed in claim 1 wherein the receiving unit comprises an antenna structure comprising a structured electrically conductive layer for receiving the electromagnetic verification signal.

5. The security element as claimed in claim 1 wherein the electronic release system checks the signal received by the receiving unit in respect of whether the signal waveform of the received signal corresponds to the specific coding, in particular the frequency and/or the amplitude of the signal has a predetermined value.

6. The security element as claimed in claim 1 wherein the electronic release system checks the signal received by the receiving unit in respect of the direction from which the signal impinges on the security element, and drives the output unit for outputting the enable signal if the signal received by the receiving unit impinges on the security element from a predetermined direction.

7. The security element as claimed in claim 1 wherein the electronic release system checks the signal received by the receiving unit in respect of whether the change in the signal waveform of the signal corresponds to the specific coding, in particular the change in the frequency, phase and/or the amplitude of the signal corresponds to predetermined values.

8. The security element as claimed in claim 1 wherein the electronic release systems checks the signal received by the receiving unit in respect of whether a code word contained in the modulated signal corresponds to the specific coding, in particular whether said code word matches a predetermined code word stored in a memory of the security element.

9. The security element as claimed in claim 1 wherein the electronic release system comprises active and/or passive organic components.

10. The security element as claimed in claim 1 wherein the electronic release system comprises one or more layers that are composed of organic conductive and/or semiconducting materials and are produced by printing technology.

11. The security element as claimed in claim 1 wherein the security element furthermore has a power apply unit.

12. The security element as claimed in claim 1 wherein the security element furthermore has a sensor unit.

13. The security element as claimed in one of the preceding claims, wherein the receiving unit, the output unit and the electronic release system form separate systems that are connected to one another via electrical contact points.

14. An identification system, comprising:

a verification device with a transmitting unit for emitting an electromagnetic verification signal containing a specific coding; and

at least one security element in the form of a flexible, multilayer film body, which security element contains a receiving unit for receiving the verification signal, an output unit for outputting an enable signal and an electronic release system having active and/or passive organic components, wherein the electronic release system is configured in such a way that it checks whether or not a signal received by the receiving unit contains the specific coding, and drives the output unit for outputting the enable signal if the signal received by the receiving unit contains the specific coding, and in that the output unit has at least one electrochromic element, a thermochromic element, an electroluminescent element, an electrophoretic element, a liquid crystal element or an organic light emitting diode.
